Four coarse wavelength-division multiplexing (CWDM) channels at 1550nm, 1570nm, 15...
1052Citations 32Altmetric Metrics Abstract Phase-change materials (PCMs) provide a unique combination of properties. On transformation from the amorphous to crystalline state, their optical properties change drastically. Short optical or electrical pulses can be utilized to switch between these states, ma...

Multiscale simulations of growth-dominated Sb 2 Te phase-change material for non-volatile photonic applications Chalcogenide phase-change materials (PCMs) are widely applied in electronic and photonic applications, such as non-volatile memory and neuro-inspired compu......
Coherent dissipative structures known as platicons can be reliably generated in photonic molecules, resulting in deterministic and reproducible microcombs derived from a continuous-wave pump. However, the supermode spectrum of standard photonic molecules
